"We usually only learn about the magnitude of an earthquake and the location of the epicenter. This infographic explains how ground waves and depth define the magnitude on the Richter Scale and the amount of destruction that implies. It also illustrates plate boundaries on the globe and the regions where most earthquakes occur. The Earthquakes infographic by Weather Underground also describes hydraulic fracking and how this has increased earthquake activity in places where earthquakes don't naturally occur."

"Teaching Resources for the Japanese Earthquake and Tsunami"

"This infographic shares the basics of tsunami's. There are three main ways that a tsunami starts, an earthquake, a landslide or a volcano. The infographic does a great job of showing how these three can begin a tsunami. The infographic then shows characteristics of a tsunami."

""Why does this matter?" Teachers are often called upon to answer this question about an academic subject, and computer science instructors may face this demand more frequently than most. Learning to write lines of code can seem, to many students, like a pointless exercise in tedium. But a few professors of computer science have a compelling reply at the ready. They are participants in the Humanitarian Free and Open Source Software project, known as HFOSS-or, more grandly, Software for Humanity. Why does this matter? these professors might respond. Because it's helping to feed needy people in Haiti, or to deliver supplies to earthquake survivors in China, or to manage the medical care of malaria victims in Rwanda."

"Your smartphone is packed with sensors and miniaturized equipment. Instead of using them to snap photos or message friends, harness those instruments for the sake of science. Software can turn a phone into a mobile science laboratory, letting you make research observations, track earthquakes, study birds and stars and the elements, and even project a virtual particle accelerator. Here are some of our favorite apps for doing science on your smartphone. "

"You see it everywhere in K-12. Kindergarteners design toys for their friends to practice empathy, while learning to use a saw and glue-gun along the way. Second graders deepen their understanding of character traits while designing and sewing puppets to represent a character in a folk-tale. In high school physics, students make wind turbines in order to internalize an understanding of how magnetism can create electricity. The "it" I'm referring to is "Making," and simply put, Making is any activity where people create something, often with their hands. I often define Making by looking at what people bring to the Maker Faire, which does include more technical aspects like 3D printing, physical computing and programming. But Making also includes woodworking, growing food, making art and crafts."
